I know OVH was the best site for renting servers like 1 or 2 years ago. Is it still the best or would you recommend another hosting service?
OVH still best for hosting?
I recommend RoozServers its OVH with UDP filters, they customize it for each game.
What the hell is roozServers? They haven't even an SSL certificate for their webpage?
Go for OVH, Hetzner, deinserverhost.de or resellers from big companies. if you want a cheap sever go with Kimsufi or Servdiscount. Depends on what you need and there area where the server will need to be located.
My own favourite is Hetzner. They offer really cheap servers with well performance (R5 3600) and great services. Don't know about their DDoS protection, but for any Gameserver I recommend using an reversed proxy.
Any answer would depend on what country or region of the World you are in , I use a Sydney based server that is part of an international company, But it might not be available in your country.
In most cases GSK Path/Tempest and GMC are the best for Rust protection wise, but if you want something cheap go for OVH. Hetzner could be even cheaper but protection feels as if there was none.
the dedicated.com seems ok, using it for year already
